Title: Manufacture of high-frequency circuit board
Inventor: MOTOKAMI MITSURU
IPC: H05K1/02
Filed: 1988-03-02
Abstract: PURPOSE:To make an easy formation of a high-frequency circuit board having such a permittivity as originally designed, by making a lot of through-holes in a dielectric board and then placing highly conductive metal on both sides of the dielectric board through dielectric films and by unifying them by applying heat and pressure. CONSTITUTION:After forming an extra-high molecular weight polyethylene sheet, through-holes of 2mm diameters are made on the whole area of the sheet to get a dielectric board having about 55% of the hole area to the whole sheet area. Then, on both sides of the dielectric board, highly conductive metal such as a rolled steel foil of 35mum in thickness and an Al foil of 1mum in thickness are unified by thermal pressing through a dielectric film of 25mum in thickness like an ethylene-vinyl copolymer hot-melt adhesive film. By this method, a high-frequency circuit board is manufactured. As the highly conductive metal, copper, Al, steel and many other metals can be used. For the thickness of the highly conductive metal, 5-2000mum is generally preferable.

Title: Head feed controller of optical disk player
Inventor: MOTOYAMA TADASHI
IPC: G11B7/095
Filed: 1983-03-25
Abstract: PURPOSE:To ensure stable reproduction regardless of the type of reproduction mode by adding the voltage obtained from a voltage generating circuit to the voltage of an LPF to drive a mirror driver, and making the tilt of a tracking mirror optimum. CONSTITUTION:The DC component voltage VD of a tracking error signal applied to a mirror driver 24 is added to the target voltage VX obtained from a voltage generating circuit 60 to obtain the voltage VC. This voltage VC is supplied to a motor 43 for head transfer mechanism to form a servo route for head transfer control. The target voltage VX is set at -VF1, -VF3, VR1 and VR3 when the forward constant speed reproduction, the forward triple speed reproduction, the reverse constant speed reproduction and the reverse triple speed reproduction are specified, respectively. Therefore, the output voltage VD of an LPF is set at zero regardless of the type of reproduction. As a result, a mirror 21 is set at an optimum tilt with which a light beam is made incident to a disk 10 through the optical axis of a lens 22 and then sent to a head 20. This ensures the stable reproduction at all times.

Title: Piezoelectric type pressure sensor
Inventor: FUKADA TETSUJI
IPC: G01L23/10
Filed: 1987-03-04
Abstract: PURPOSE:To make the apparatus suitable for mass production with a reduction in variations between sensors, by applying a pressure with a pressure transmitting member to make a shearing stress work on both end faces of a cylindrical piezoelectric element. CONSTITUTION:A cylindrical piezoelectric element 3 is provided on the inner surface of a box 1 with such a mounting construction that a pressure receiving surface 1' is positioned within an area to be measured. The element 3 has a thickness-wise polari zation axis with the internal and external circumferential surfaces serving as electrode. The external circumference portion of the end face of the element is fixed with a fixing member 4 while a pressure is applied to the internal circumference of the other end face with a pressure transmitting member 2 so that a stress works in the direction of shearing to the polarization axis. Thus, a contact surface is reduced between members for fixing both ends thereof to lessen effect on heat. An electric circuit 6 is built on a ceramic substrate 5 excellent in the heat resistance and an output of the element 3 is subjected to an impedance conversion and taken out after amplified to enhance the resistance to noise. This also achieves a higher machining accuracy simply at both ends of the fixed element 3 thereby increasing the force per unit area with the application of an uniform force.
